The following diagrams illustrate two examples of the 'key and lock' mechanism - how an enzyme works. The active site is where the chemical change from substrate to product takes place and its shape is very important. The mechanism is discussed in more detail in the next section.. The traditional Emil Fisher's 'lock-key' model uses analogy between enzyme (lock) and substrate (key) to describe the need for a matching shape of a substrate in order to fit to the active site of an enzyme [20].
